Specification of Letters Patent.

Patented Aug. 31, 1909.

Application filed February 12, 1908. Serial No. 415,519.

To all whom it may concern:

Be it known that I, J osnrn: C. Kunz, citizen of the United States,residing at Fresno, inthe county of Fresno and State of California, haveinvented certain new and useful Improvements in Lawn-Sprinklers, ofwhich the following is a specification.

My invention relates to hydraulic appliances and has special referenceto sprinkling devices adapted to be attached to hose used indistributing water over lawns and gardens.

The chief objects of my improvements are to provide a water {sprinklingor spraying device for use with lawn and garden hose that willdistribute the water in a suitable manner over a well defined oblongarea or strip of the surfaceof a lawn or garden, instead of in circularpatches concentric to the location of the hose nozzle, as is the commonresultin all similar apparatus; to furnish a simple, efficient, anddurable device for the purpose stated, and to supply a water sprayingdevice that can be readily attached to hose in common use,-and, havingfew parts, can be economically manufactured. .1

I accomplish the above objects by means of the apparatus illustrated inthe accompanying drawing which forms a part of this application and inwhich Figure 1 is a side elevation of my improved sprinkling device,attached to a base plate; Fig. 2 is a longitudinal section on the line22 of Fig. 1, the base platebeing removed. Fig. 3 is a perspectiveviewof the deflecting vane; Fig. 4: is-a plan view of the blank for thevane, previous to beingbent into its final form; Fig. 5 is a top planview of the stop, and Fig. 6 is a side eleva tion. of one of the pivotlugs.

Referring to the details of the drawing, the reference numerals 7indicate a block or base plate, having a bore 8 provided with standardthreads 8 for the attachment of an ordinary hose. The bore 8 extends tothe center of the block and then passes upward through a nipple 9,provided with standard threads 9 A staple 7: serves for the attachmentof a cord for shifting the block as required by pulling it along theground.

The numeral 10 indicates a base, rectangular in outline, provided with acylindrical projection or boss 11 which has a socket 11 furnished withthreads adapted to engage the standard threads 9'" on the nipple 9.Concentric with said socket the base is bored for the insertion of atube or nozzle 12 suitably reduced in size from the socket diameter toincrease the initial velocity of the stream as it issues from theorifice 'of said nozzle. The nozzle 12 may be formed integral with saidbase if desired, but I prefer to insert a section of tubing, asillustrated in Fig. 2. Diametrically opposite each other upon the upperface of'said .base are erected standards 13, bent at right angles at thelower ends to form feet or flanges 14, and

secured to said base by screws 15. Between said standards and supportedtherein in a manner hereinafter described is located a deflecting plateor vane 16 formed of a single piece of metal, rectangular in outline asshown in the blank illustrated in Fig. 4 and approximately twice thelength the part is to be when completed. The corners of the plate thusprepared are slightly clipped or rounded and extending through theextreme margins at the ends near each corner are formed slits or cuts17, slightly inclined to the said margins. The corners of the plate 16are bent on the lines 17 at a right angle with the plate surface, toform triangular flanges 18,,and the ends or flaps 19, formed by the cutsor slits 17, are curved in the same direction as'the said flanges 18 arebent, as shown at 20 in Figs. 2 and 3. The center of the blank 17 isprovided with a diamondshaped opening 21 and thesaid blank is then bentupon itself-on the line 21 until the two parts are in apposition, backto back, as shown. The redundant projecting corners 18 may be removed soas to conform to the curve of the flaps 20 and show a finished 7appearance as in Fig. 3. When the plate is thus bent upon the line 21,the central opening 21 will assume the appearance seen in Figs. 1 and 3,forming a triangular notch 22 in the lower edge of the plate 16 wherefolded. The said plate is furnished with lugs 23, having notches 23,which engage the lateral margins of said plate, and are swaged firmlythereon, serving a double purpose, of clamps to hold the laminae of thefolded plate securely in apposition and also acting as journals orpivots, ,by engaging holes near the upper ends of the standards 13. Bythis arrangement, the said plate or vane 16 will swing to and fro uponits pivots23 in the supports 13 when acted upon same forces it will'finer jets or films, and the by the stream from the nozzle 12, in amanner hereinafter set forth, the notch 22 affording suflicientclearance so as to interfere with the said nozzle. When in operation itis necessary to limit the vibrations of the said plate and to this end Iprovide a stop 24, which consists of a plate bent as at 25, the ends 26being oppositely inclined as shown in Figs. 2 and 5, the angle of suchinclination corresponding to the direction taken by the vane at eachlimit of its vibration,as shown in Fig. 2, where the said vane seen'inapposition with one stop flange 26, the alternate position of the vanebeing shown in dotted lines. The said stop member 24. isapplied toeither standard 13 at a suitable height, the said bends or loops 25engaging the marginsof the standard, and the device is then clampedfirmly in place by the thumb screw 27. By moving the said stop 24 up ordown upon the standard the oscillations of said vane 16 may be variedwithin sufficient limits.

Having thus described the details of construction of my improvedspraying device I will briefly outline the method of its operation: Thebase can be readily applied to the nipple 9 of an ordinary hose couplingby screwing it thereon by hand, no wrench or other tool being required,since theoblong shape of the plate 10 affords a suflicient hand grasp.lVith the base thus applied, when a stream of water issues underpressure from the pipe 12 it will impinge against one face of the vane16 and the stream will be slightly deflected following the face of thesaid plate, and upon reaching that part of the plate above the fulcrumor axis 23 the force of the stream will tilt the plate in the oppositedirection. Being met upon this side by the immediately swing back again,and this vibration of the plate or vane will continue so long as thestream flows with sufficient pressure. The curved flanges or flaps20-supplement and intensify the actionabove described, tending inaddition to break the main body of the stream into side flanges 18 acttocontrol the. deviation laterally, so that the distribution of the spraywill be confined to a comparatively narrow oblong strip, instead of acircle as with ordinary sprinklers. This ability to send the spray inright lines, instead of concentrically, will be especially useful alongwalks and borders, and wherever the margins of the plate to be wateredare straight, not only avoidingencroachment upon parts where thesprinkling would be objectionable but also serving to economize both:time and water.

Having thus described my invention what I claim is p 1. In a lawnsprinkler, the combination with a base adapted to be attached to a hose,and a nozzle, of an oscillating deflector having its axis intersectingthe axis of said nozzle, said deflector adapted to be oscillated by thestream from said nozzle.

2. In a lawn sprinkler, the combination with a nozzle of a planedeflector adapted to be oscillated by the impact of the stream from saidnozzle, said deflector having its axis intersecting the axis of thenozzle, and means for limiting the oscillating movements of thedeflector.

3. In a lawn-sprinkler, the combination with a nozzle, of a deflectingvane mounted to oscillate upon an axis intersecting the axis ofsaidnozzle, said vane adapted to be operated by the imnact of the streamfrom the nozzle, and an adjustable stop for limiting the movements ofsaid vane.

41;. In a sprinkler adapted to be attached to a base plate,thecombination of a nozzle, a vane mounted to swing upon an axis at aright angle to the longitudinal axis of said nozzle, a stop for limitingthe oscillation of said vane,.and means for adjusting said stop.

5.111 a sprinkling device adapted to be usedwith a hose, the combinationof a supporting base, a nozzle, a vane arranged to swing upon an axistransverse to the axis of said nozzle, lateral flanges for the vane, andan adjustable stop for limiting the oscillations of saidvane.

6. In. a sprinkler including a base-plate adapted to be attached to anozzle, an oscillating-vane adapted to be operated by the impact of thestream from the nozzle, supports for the vane attached to thebase-plate, and a stop adjustable on one of said supports.

7; In a spninkler, including a base-plate adapted 'to be attached to anozzle, an oscillating vane adapted" to be operated by the impact of thestream from the nozzle, said vane consisting of a rectangular membenformed of'a single plate bent upon itself in the median line, andha'vingthe endsof the bent plate curved in opposite directions, and sideflanges bent at right-angles with the main plate, supports for the vanemounted on said base-plate, anda stop for limiting theosci lla-tion ofsaid vane.

In testimony whereof-I aflixmy signature in the'prcsence of twowitnesses.
